What do spiders eat?

Answer:

Virtually all spiders are predatory on other animals, especially insects and other spiders. Very large spiders are capable of preying on small vertebrate animals such as lizards, frogs, fish, tadpoles, or even small snakes or baby rodents. Large orb weavers have been observed to occasionally ensnare small birds or bats. Recently, a jumping spider was discovered in Central America that feeds mostly on special fruiting bodies on acacia trees. This vegetarian appetite is quite atypical. Still, male flower crab spiders, Misumena vatia, are known to feed on pollen in the flowers where they sit and wait for insects (and females of their own species).
